LTC4061-4.4 - Standalone Linear Li-Ion Battery Charger

Download the LTC4061-4.4 datasheet PDF. This datasheet also covers the LTC4061-44 variant, as both devices belong to the same standalone linear li-ion battery charger family and are provided as variant models within a single manufacturer datasheet.

Key Features

  • designed to maximize battery lifetime and reliability include NTC battery temperature sensing and the SmartStart charging algorithm. No external sense resistor or external blocking diode is required for charging due to the internal MOSFET architecture. Internal thermal feedback regulates the charge current to maintain a constant die temperature during high power operation or high ambient temperature conditions. The charge current is programmed with an external resistor. With power applied, the L.
